Why does the water flow weakly at the filtered setting?

If the water flow weakly at the filtered setting, it may be caused by two reasons.
Possible causes and solutions:

* The water pressure is lower than the minimum required. Please adjust the faucet and increase the inlet water pressure. 

* The filter cartridge is clogged. If the filter cartridge is clogged,  please replace it with a cartridge of the original type. 

Tip: To prevent the filter cartridge from clogging up, let the water run at unfiltered settings for 5 seconds before every use.
